SUPPORT FOR RAILROAD-RAILS.

SPECIFICATION forming part of Letters Patent No. 430,590, dated June 17,1890. Application filed December 3, 1888. Serial No. 292,486. (Nomodel.)

To all whom it may concern:

Be it known that LJAMES M, PRICE, a'citizen of the United States,residing' in the city and county of Philadelphia, State of Pennsylvania,have invented a new and useful Im provenient in Supports forRailroad-Rails, which improvement is fully set forth in the followingspecification and accompanying drawings.

My Invention consists of means forsupporting railroad-rails in lieu ofwooden crossties and stringers, the same embodying trusses formed ofmetal, as will be hereinafter fully set forth and claimed.

It also consists of means, substantially as described, for connectingthe stringers, whereby the same are braced in lateral directions andprevented from spreading.

It also consists of means, substantially as described, for connectingthe rails with the stringers in a firm and durable manner. e

It also consists of means, substantially as described, whereby the headand foot or members of each truss of the stringer are strengthened.

It also consists of the construction and combination of various parts,as will be' described and claimed, adapting the stringers fgr elevatedroads, street-car tracks, bridges,

Fig. 3 represents a top or plan View thereof. Figs. 4and 5 represent transverse vertical sections of modifications onenlarged scales. Fig. 6 represents a perspective view of a bed on whichthe rail is supported and the means for clamping the said rail. Fig. 7represents a side elevation of the truss serviceable for elevated roads,bridges, &e. Fig. 8 represents a transverse vertical section thereof online y y, Fig. 7. Fig. 9 represents a side elevation of a form of trussserviceable for streetrails. Fig. l0 represents a transverse sectionthereof on line z z, Fig. f). Figs. lland l2 represent vertical sectionsof modifications. Fig.13 represents a horizontal section online a a,Fig. l2. Figs.` 14: and 15 represent side elevations of couplings forthe members of the trussed stringer embodying Iny invention.

Similar letters and numerals of reference indicate corresponding partsin the several figures.

Referring to the drawings, A designates stringers on whichrailroad-rails are supported, the same being formed of suitable metalbent or rolled into the shape of trusses 6o or alternately inverted,producing the heads l, to which the rails are secured, and feet 2 as thebases of the stringers.

C C designate transverselyextending clamps, which are secured,respectively, to the heads and bases of the trusses of the stringers,said clamps being also formed with cheekpieces 3, which embrace theouter sides of the heads l and the bases of the rails. rllhe inner sidesof said heads are connected with clamps 7o C by means of bolts 4, whoseheads bear against the flanges of the rails on the sides opposite to thecheek-pieces 3, by which means the rails are lirmly connected with thetrusses, and the upper parts of the pair of are held properly A apart`and braced and 8o strengthened in lateral directions, thus producingastrong structure. The stringers will be suitably ballasted, as shown inFig. l, whereby the heads of the trusses willreceive additional support,and thereby be better enabled to endure the strain superimposed upon thesame.

In order to provide a wider footing for the stringers upon the ballastunderneath, I employ bars 6, which are channeled to receive 9o the basesof the trusses and extend in transverse direction, connecting the pairof stringers, and are connected thereto, as seen in Fig. 3, one of saidbars being shown in side elevation by the dotted ligure at the right ofsaid Fig. 3.

In Figs. l, 2, and 3 the stringers are shown as formed of fiat metalwith channels 7 on the upper faces of the heads of the stringers toreceive the bases of the rails.

In Fig. 4 the stringers are shown made of round metal, and in Fig. 5they are shown IOO made of angle-iron. interposed between the bases ofthe rails and thetrussed stringers in said Figs. et and 5 are bed-plates9, (see also Fig. 6,) the same resting on the heads of the strin gers ortrusses and being bolted or otherwise secured thereto. The clamps C C inthese cases are grooved on their upper and under sides to receive,respectively, the heads and feet of the trusses, the ends of the clampshaving cheek-pieces 3, which embrace the bedpieces and base of therails, which, in connection with ren'iovable cheek-pieces 10 opposite tothe cheek-pieces 3 and bolts 11, firmly connect the rails, bed-pieces,and clamps with the trusses. Connected with the heads and feet of thetrusses, as in Figs. 7, 8, 9, and 10, are additional stringers D D,whichextend in the longitudinal direction of the same, and are bolted orriveted thereto, adapting the stringers for elevated roads and bridgesand without ballast for street use.

The rail in Figs. '7 and S rests in the Stringer D, andthe clamps Cembrace the heads 1 of thetrusses, the'base of the rail, and theadditional stringer D, the several parts being properly bolted togetheron each side of the flange.

In Figs. 9 and 10 the additional stringcr D is shown as supporting astreet-car rail.

In Figs. 11 and 12 the heads 1 of the trusses are shown in sectionheavily shaded, with shoulders and .grooves on their upper and lowerfaces, so as to interlock with the clamps C and cheek-pieces 12 `of therail-fastening.

Each truss in Figs. 1, 2 and 3 is formed in one piece, the heads andfeet thereof being contiguous to each other; but where themembers of thetrusses are made separate, or Where two stringers come together, theyare connected by coupling-pieces 13, as in Figs. 14 and 15,the ends ofthe feet or of the heads, or both, being secured to said pieces.

The flat stringers, Figs. 1, 2, and 3, may be constituted of one or morepieces, as seen in transverse section, moving longitudinally of thevtrack and bound together by clamp and bed plates, as hereinafterdescribed.

The stringers A may be rolled or produced in any other suitable mannerin long or short sections or pieces or individual trusses connectedaccording to the lengt-h required, it being seen that the stringerspresent a structure which in longitudinall direction is of the form ofcrimps or corrugations, arches and reversed arches, or truncatedpyramids and reversed truncated pyramids, thereby producing a strong andiirm support for the rails, the same being vastly more durable thanwooden ties and stringers, one that may be quickly and easily laid andis not of eX- pensive nature, is uniformly elastic, and causessmoothness of running the cars thereon. Owing to the uniform elasticityof every section of these stringers, whether the fiat summit or the iiatbase of any section corresponding to the woodeny cross-tic in itsfunction is midway of the section ornot, the joint of the rails may beadvantageously made on these summits instead of between cross-ties, ascommonly done to insure the needful elasticity.

To prevent the rails from sliding longitudinally upon the summitsbecause ot' not being bolted together through transverse holes 1n theweb, I notch the flange ot` each rail near its end, and thus twoprojections or nipples on the underside of the br'oad cheek-piece ortrack-plate, Fig. 13, engage with these notches or slots in the flangeot each rail, permitting but limiting the expansion and contraction ofthe rails. This secures a continuous rail without using the expensive{ish-plates now employed and without piercing the web.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is
